The purpose of the company is to provide electrical consulting (MV & LV) / PFC / protection / power & power quality solutions to customers in terms of specialized equipment integration in old and new plants in order to provide efficient and high performance power systems.

Company member and associates

The company is founded and managed by Paul du Randt who is experienced in power system protection (12 years), power system management / engineering (3 years), power factor correction, power management and power quality solutions (10 years). Paul is registered as a Professional Technologist with the Engineering Council of South Africa. The employees of the company are highly skilled and experienced in various activities. This provides a team of individuals with skills from solution creation to full completion. The company has a strong innovative drive and is known to deliver with high energy and professionalism.

Power system optimization and audits.

Industry is continuously extending their production and energy is one of the raw materials provided to the product. Due to the continuous equipment aging, change in load requirements capacity management need to be considered. The quality and losses in production is influenced by the power quality provided. We at HT specialize in detecting, rectifying power quality and production problems.

HT was founded out of the need to measure and analyse PFC, power quality delivery and providing solutions to reduce production loss for industrial plants. Measurement is done with monitoring voltage and current providing system and loading information. The measurements are designed to provide information to design possible solutions. Load conditions are analysed with the performance of the equipment used in the load-installed base.

The company was founded in 2002 and has competed studies on the following type of customers, hospitals, telecommunications, utilities, food and many more. The main target markets are companies that loose production due to dips, brownouts or outages that result in production loss. We provide solutions for internal and external site power quality problems.

Power Factor Correction

More information about reactive power and power factor correction

In power factor correction systems the reactive current and the corres - ponding reactive power drawn by consumers will be compensated by the means of PFC capacitors.

What is Power Factor Correction?

Reactive power is necessary for the generation of electromagnetic fields. Because these fields continuously develop and reduce, the reactive power fluctuates between producers and users. In contrast to active power, reactive power they cannot be used i.e. cannot be converted into another form of energy and strain the electricity supply network and the production equipment (generators and transformers). Furthermore, all energy distribution systems must be constructed larger for the allocation of reactive currents.
It is, therefore, necessary to reduce the same amount of occurring inductive reactive power near to the consumer with a capacitive reactive power. This process is called compensation. During compensation, the ratio of reactive power in the network reduces by the reactive power of the power capacitor or the PFC system. The energy generation systems and the energy transmission systems are, therefore, discharged from reactive currents.

Use reliability is ensured by its AC measurement and waveform recording, and automatic detection is performed after the relay test set start running, which are independently developed by Kingsine Electric Automation Co.Ltd.

Adopt 100M network card to transport data between computer and tester, at the same time the software of tester can be upgraded by USB, so the speed is improved greatly either report submission or software upgrade.
